OpenWrt support for TP-Link ac1900 TL-WDR7661

For Developers

I have a TP-Link ac1900 TL-WDR7661 router.
Do I have to install AC1200 or AC1750 or WDR7500 OpenWrt firmware on this router?

And if the router ac1900 TL-WDR7661 does not have support for OpenWrt, can you please support it?

If it's not there, it's not supported https://openwrt.org/toh/start
